iPhone XR 故障排除

Phone is ridiculously slow at loading contacts, finding contacts. Constantly freezing. 3 times to Apple support. Once in store. Told me to wait for a software update. No progress. This happened from day one on a brand new phone. 3 months later no progress. Apple do not seem keen to offer new phone. Any ideas? Thanks in advance

The ringer volum won’t stay up . I raise the volumn and it immediately goes back to off as I’m watching. Apple store re set my phone but it didn’t help. Tech said if that didn’t work it probable was a hardware issue and the phone would have to be replaced. Any suggestions?

is this a common problem with the XR?

my iphone xr microphone is not working during phone calls.. although siri still working and mic works while recording a video but doesnt work on voice memos? is it my mic or software glitch ? any ideas ??

Back in April I had put my phone was on the wireless charger, to begin updating it while I slept. I woke up to a looping phone. I put it in restore mode and it has been stuck there ever since. I have tried everything I could find on Apple forums, Reddit, Google, I purchased IMyFone, and purchased new MFI thunderbolt cables and adapters. I cannot tell if it is a lost cause, but it actually has made progress in how far the restore has gotten before giving me error codes too! it is a mint condition Iphone XR and I can’t seem to give it up. I refuse to pay Apple $424 for their own defect and any advise you can give is greatly appreciated.
